I'm sorry, I'm not sure, but try your best!
Answer:
A = -1, 1
B= 0, -2
C= -2, -1
Step-by-step explanation:
originally the coordinates are x, y but if it is reflect over the line y = - x which will now turn your coordinates to (-y, -x)
C=2piR. C=2(3.14)(8.2). C=6.28(8.2). C= 51.496. But we have to round to the nearest hundredth which is the second place to the right of a decimal. So now C=51.50 (since 49+1=50) :) hope this helps
